IMPROVEMENT IN HlLLlNG-PLOWS.

Specification forming part of Letters Patent No. 201,099, dated March12, 1878 application filed January 22, 1878.

To all whom it may concern:

Be it known that I, GEORGE A. DE LONG, of Weedsport, New York, haveinvented certain Improvements in Hilling-Plows, of which the followingis a specification:

The improvements herein described relate to the manner of affixing thepoint and beam to the mold-board, attachments for wings by which themold-board is strengthened and braced, and also in the manner ofattaching the handles, by which improvements in construction greaterstrength and permanence are given to the parts, facilitating themolding, casting, and fitting them together, and cheapening andexpediting the manufacture. A part of these devices are adapted to otherplows.

The construction is as follows, reference being had in the descriptionto the accompanying drawings, which show, in Figure 1, a side elevationof the 'plow; Fig. 2, a plan of the under side of the point, mold-board,and beam united; Fig. 3, the beam and shoe detached and, in Fig. 4, atop view of mold-board, showing plan of ears or braces f, to hold andbrace the beam in place.

The double-winged mold-board a has a projection, b, on its inner face,projecting beyond its front line under the point 0, which rests on andis affixed to it (see Fig. 2) by means of a screw-bolt, which is castinto the point without projecting through to its face, and a nut, c.This bolt passes through a hole in the projection I), which is so formedas to allow the point to slip into place and lock with the mold-board,and be drawn tight by the not 0'.

There are projections d d from the edges of the mold-board and point, onthe under side, to securely hold them in place by the use of a singlebolt. The wings of the mold-board are strengthened by dovetail cleats ate e, that serve to attach extension-wings of wood or metal when needed.

At the upper angle, where the wings meet, two ears or braces, f f, arecast, forming a dovetail recess, into which the beam slides and fits,and by which it is braced and held into a socket in projection I), caston the moldboard.

The beam is of curved form, (shown in Fig. 3,) with a side beading atits edges, formed in front to fit the space between the ears ff. Thebeam has a projection on each side, where the bolt h passes through it,for fitting up in the recess, to save filing. There is a projection, p,on the front edge of the beam, just over the upper edge of themold-board, to form a continuous outline therewith, to prevent clogging.Just above this point p a loop, 1', is formed on each side of the beam,to fit the ends of the handles into, and in rear .thereof a spreader, k,is formed on the beam, against which the handles bear, and are affixedby a horizontal bolt at Z.

By the above-described construction of parts it will be seen that theyare each securely united by a single bolt, and that none of the boltscome through to the wearing-surface, by which any clogging therefrom isavoided. There is a heel-piece cast on the beam, onto which a shoe, m,is fitted and supported, forward and back, by proper projections on theheel-piece. A bolt at n passes "through the sides of the shoe andheel-piece, to hold them together.

Having thus fully described my improvements, I claim- 1. The mold-boardto, having ears f f on the inner face for embracing the beam, and a bossor projection, b, forming a socket for securing the lower end of thebeam, substantially in the manner and for the purposes specified.

2. The beam constructed as herein specified, and combined with'themold-board by looking into the ears f and socket b, so that they can befirmly united by a single bolt, substantially as herein set forth.

GEORGE A. DE LONG.
